Abstract: Ceramic based oxygen transport membranes (OTM) have attracted much attention for alternative production concepts to generate high purity oxygen at low energy consumption, particularly if good thermal integration in high-temperature industrial process is realized. For a practical application relevant design, an asymmetric membrane consisting of a thin dense membrane layer supported by a porous substrate was in the focus of the current research. To ensure long-term operation and lifetime, the membrane must maintain both its mechanical stability and functional property. However, strength of the mechanically supporting substrate material usually decreases with increasing total pore volume even though high porosity may enhance the functional properties, such as permeability. Besides, differences in thermo-mechanical behavior, in particular creep, of dense and porous membrane material may also lead to structure instability. Hence, the main purpose of the present work is to study the porosity dependency of thermal-mechanical properties of selected oxygen transport membrane materials, and the mechanical compatibility of the porous / dense membrane layers in the asymmetric membrane design.
